Rear axle housing repair sleeves not hardened

[dennis lumbert]

I had rear axle housings machined and installed replacement races in 08.Car has 1600 miles on it and inspected brakes to discover grease colored like silver.After inspection found wear on housing races only.Checked them for hardness with a file and their soft.I removed the sleeves and the housings are both machined to 1.752”.The sleeves appear to have had an inner diameter of 1.750”.purchased replacements from Bert’s and they are 1.695” inner diameter.
I moved to Ar in 15 so I have to find someone here to have them both remachined .A local machinest wants a min of $170.00 each to do the job.I was hoping to find sleeves the same size as the ones I removed but that may be impossible.Not saying the price is to high ,just was hoping to not have to Machine the housings again.Has anyone run across sleeves with a 1.750 inner diameter?
